🚀 n8n Scalable Railway Template

This project provides a production-grade, scalable n8n setup optimized for the Railway platform.
It includes a multi-service architecture designed for performance, fault-tolerance, and high-throughput automation workloads.

Deploy and Host

Deploy this template directly on Railway to get a fully isolated and scalable multi-service n8n infrastructure.
Railway will automatically provision the Editor, Worker, Webhook, PostgreSQL, and Valkey services with zero manual setup.

About Hosting

This template is designed specifically for production hosting on Railway, ensuring:

• Automatic resource provisioning
• Service isolation
• Secure environment variable handling
• Automatic HTTPS via Railway domains
• Horizontal scaling for Worker and Webhook services
• Built-in persistent storage for PostgreSQL

Everything is preconfigured for real-world, enterprise-grade workloads.

Why Deploy

Deploying this template gives you:

• A stable, production-ready n8n architecture
• Distributed execution using Workers
• Reliable Webhook processing under high load
• Automatic queuing via Redis/Valkey
• A secure and isolated environment
• Zero infrastructure maintenance

Perfect for users who need automation at scale without managing servers manually.

Common Use Cases

This template is ideal for:

• High-volume webhook ingestion
• Automation pipelines and backend orchestration
• Large-scale multi-step workflows
• AI agent orchestration
• Event-driven applications
• Cron, polling, and scraping tasks
• Enterprise integrations requiring fault tolerance

Dependencies for

This template includes and depends on the following core components:

Deployment Dependencies

• Railway Postgres – persistent storage for workflows, executions, and credentials
• Railway Valkey (Redis) – BullMQ job queue backend
• n8n Editor Service – main UI and configuration
• n8n Worker Service – distributed execution engine
• n8n Webhook Service – high-performance webhook receiver
• Railway Domains – automatic HTTPS and routing

All dependencies are automatically created and linked during deployment.

📌 Features

• Editor Service – Main n8n interface
• Worker Service – Dedicated workflow execution workers
• Webhook Service – High-performance webhook processing endpoint
• PostgreSQL – Persistent workflow and credential storage
• Valkey (Redis) – Queue backend for distributed job execution
• Automatic Secrets – Encryption keys generated automatically
• Fully Isolated Services – Editor, Worker, Webhook all managed independently

🧩 Architecture Overview

Editor → Worker → Webhook
└── PostgreSQL
└── Valkey (Redis)

• Editor handles UI, workflows, credentials, and manual executions
• Worker executes jobs asynchronously using queue-based execution
• Webhook receives external HTTP callbacks at scale
• PostgreSQL stores workflows, executions, credentials
• Valkey powers distributed execution via BullMQ queues

🔧 Environment Variables

Automatically Provided by Railway

• Database host, port, user, password
• Valkey (Redis) host, port, password
• Public domain references
• Encryption key (${{secret(64)}})

User-Provided (SMTP)

• N8N_SMTP_HOST
• N8N_SMTP_PORT
• N8N_SMTP_USER
• N8N_SMTP_PASS
• N8N_SMTP_SENDER
• N8N_EMAIL_MODE (default: smtp)

All other environment variables are preconfigured for a secure and scalable deployment.

🚀 Deployment Steps

1. Click Deploy on Railway
2. Railway automatically provisions:
   • Editor, Worker, Webhook
   • PostgreSQL
   • Valkey (Redis)
3. Fill only the required SMTP envs
4. Your production automation platform is ready

🛡 Security

• Credentials encrypted using a 64-byte encryption key
• Secure cookies enabled
• Production-hardening enabled
• Public API endpoints disabled by default
• Database SSL enforced

🧑‍💻 Maintainer

Built and maintained by Kal-EL Dias.
This architecture reflects the same deployment patterns I personally use for high-volume, large-scale automation systems in real client and enterprise projects.
Future updates may include version upgrades, security enhancements, and infra improvements as the n8n and Railway ecosystems evolve.
